Salt River Project Selects OSI Technology for Its Next-Generation Energy Management System

Open Systems International, Inc. has been awarded a contract by the Salt River Project of Phoenix, Arizona, to supply SRP’s next-generation energy management system (EMS).

SRP provides electricity to more than 890,000 customers in the greater Phoenix metropolitan area. It is part of the critical Southwestern transmission grid that includes large inter-area transfers due to the unprecedented growth in the Southwestern United States. This growth and mandated new industry regulations necessitate a modern and reliable open system solution that not only supports large transmission and generation monitoring and control operations, but also provides for more frequent, seamless and less cumbersome technology upgrades.

SRP’s main motivation for embarking on this new project was the implementation of a modern and secure operations control system based on an “open system architecture” that facilitates future upgrades of hardware and software as well as a lower recurring maintenance costs. SRP’s objectives were met with OSI’s monarch EMS architecture and implementation strategy.

The proposed system is based on OSI’s monarch distributed open architecture and includes Supervisory Control and Data Acquisition, Automatic Generation Control and Dispatch (AGC), Historical Information System, Transmission Network Analysis, Operator Training Simulator, Secure ICCP communications, and interfaces with CAISO, WECC, and various enterprise systems. The project implementation is based on OSI’s Rapid Project Methodology (RPM) and is planned for a record completion of 10 months.
